> NHTSA strongly encourages States not to codify this Voluntary Guidance (that is, incorporate it into State statutes) as a legal requirement for any phases of development, testing, or deployment of ADSs. Allowing NHTSA alone to regulate the safety design and performance aspects of ADS technology will help avoid conflicting Federal and State laws and regulations that could impede deployment.

Can someone clarify that this please? To me it appears that this body is saying that, "States, Please don't make laws requiring minimal standards for SDVs for things, including deployment on public roads, because that would impede deployment. Allow us to handle all that"

But they didn't do it, right? SDV's were on roads even before the "safety design and performance aspects of ADS technology" was regulated, right?
